To all whom "it may 00:10am:

Be it known that l, SAMUEL J. ()AKES, a

citizen of the United States of .'\nierica, re- 1 siding at; Boston, in the county of Suffolk and State of lvlasszu'hnsetts, have invented new and useful Improvements in Brakes, of which they following: is a spe itieation.

My invention relates to brakes, and its primary object is to provide a device t eharzu-ter WiilPll is eh-peeially designid ior use on automobiles in; an auxiliary brake, and by meani-s or which nutoi'nobiles may be held against. movement when stopped on an im-line.

A further obieet of my invention is to provide :1 hr: he \Vllh'll simple o't' construction, which may be niaimfuetured and sold at a eompuratively low cost, and whirh may be readily attached to an automobile of any ronstruction.

A still further object of my invention is I to n'ovide a brake which is eapable. of being at all times mider full control of the oper ator of the automobihi.

li ith the above and other objects in vieug the invention consists: in the construction combination and arrangement, of parts hereinuiter hilly :leserilnrtl, rluimod and illustra l in the aeeompanying drawing, wherein:

Figure 1 is 2 view in side elevation, illustrating the a plieatiou of my improved brake. Fig. 3 is a view in aide elevation of the brake. Fig. 3 is a top plan view thereof, and Fig. is a plun view of a portion of one end o't' n Shaft Metering to the drawing by reference noun-rots. :2 (liFlgliiittm an uutomohiie of a well known eoustrnetiou. and designates 0 one of a pair of bearing; hraekots whieh are serured to and depend from the floor of the .ltlillllflflflli. A shalt t has its ends reduced to pro ide journals; 5. said journals being I adopted to be received by the hearings 6 of l the brat-hot 1 3. (hock levers 4 are mounted on the shaft 4 for relatively independent upwurd movements thereon. The downward moven'ient of the ehor-ic levers is; limited by meme; of lugs undo oi which project. from the the shaft 1- at points beneath the oi d rhoeh levers. Each of the tuna one oi in: ends provided 5: h ulapi'ed to irl'ie, shaft and are adapted to engage the v i anted or.

facilitate its engagement with the ground. I The (llUt'lC levers 7 are mounted upon the journals 5 between the ends of the shu'ftgt and the braeltets 1 thereby obviating the nerosflit v of the use of nuts or other fastenin; devices for securingthe levers in applied position. When the (hook lever 7 are in operative position, the free ends are yieldingly held in engagement with the ground by :neam, of contractile springs 10, one only of the springs being; hll(l\vll. One end of i eaeh of the springs 10 is; swm'ed to the lever and the other end to the uutomobile. The L ohoek levers T are adapted to be moved into and supported in inoperative position by means of a foot lever ll, whirl! is pivotully mounted to position its power end 12 in convenient rem-h ol' the operator of the auto mobile and its operating end 13 at a point below the floor of the automobile. A cable t-r, passing over pulleys if), has one of its ends secured to the operating end 1?) of the lever 11 and its other end to rearwardly projecting arm 16 seoured to'the shaft 4. The connection between the lever 11 and the shaft 4 is such that when a downward pressure is applied to the power end 12 of the lever, the shaft is: turned on its: journal and the choek lovers 7 elevated through the medium of the lug T. A spring pressed dog 17 is mounted for automatic engagement with :1 lug 'lS-on the lever 11, and it adapted to retain the chock levers T in inoperative position. The do;, 17 is provided with a tail piece 19 which extends above the power end 12 ot' the lever 11, whereby the dog may be thrown out of engagen'ient with the hip; 18 by the foot of the operator when it is desired to use the brake. ASSOOH as the lever '11 is released. the spring 10 moves the free ends of the, chock levers 7 into engagement with the ground, and rocks tho shaft. 4 on'its ionrnals through themedium of the lugs T. This movement of the shaft moves the power end 12 ot the lever 11 in proper position for the application of the power to move the cheek lovers 7 into inoperative position. the chm-k lovers 7 project in a ['(tllVtll'fl direction, the brake may he used while uni-ending an incline to stop the uutomol'iilo i should an aei-ident occur. and us said levers inlay have relatively indepeni lent forward ,aee oi the o'round are :duo adapted to in :i!(% is stopped on :an

brake shaft, cnim'eetimi between the arm and foot lever, and means adapted to the foot iei ei' to retain the cheek position. Y I

3. A vehicle brake including a rotatabiy mounted shaft, a check lever piveteiiy mountigicline, and it may, desired, be asset with tnemrdinary wheel brake pf an automobile, Should the automobile he stopped on an im ciine, the brake will prevent 10st rearward motion during the starting {of the engme.

Frem the foregoing" escriytien in ceimeetion with the accompanying (imwiiw, the construction and mode of operation at the invention should be undei'steeei without a further: extended ciescription.

(Changes in the term, propertions and minor ieteiis of coiistiiictien may be made within the ecope of the claims Without tie. parting fremthe snirit or sacrificing any of the advantages 0;? the inventien.

Having fully deseiiitaeii and i lustrated my invention, What It claim as new is:

1. A brake inciudizzg a, shaft provided withjoui'neis and legs, etaeek levers pivotailymouiited 0n the jouineis above the lugs and having theiiv endsferked, means by which the may centrelied, and ineengwedapted t0 yieidingiy retain the chock levers in engagement with the ground.

A brake including a shaft, chock levers pivot-ally mounted thereon, lugs on the shaft adapted for engagement with the chock ievet's, means edepteei i0 yieidingiy retain the aim-e ieverg in new; with the gmund, a pivotaii'y mounted liOi I iever, an arm on the levers in ineperative and means by which the $319.72; is 1.0; secured te the 5.
